Discrete output wiring

Discrete output (DO) wiring depends on whether you are wiring terminals 3 and 4 (Channel B) or
terminals 5 and 6 (Channel C), and also on whether you have configured the terminals for internal or
external power. The following diagrams are examples of proper wiring for these configurations:
• Channel B, internal power – Figure 6-9
• Channel B, external power – Figure 6-10
• Channel C, internal power – Figure 6-11
• Channel C, external power – Figure 6-12

Total load
Note: See Figure 6-13 for output
voltage versus load information.
Figure 6-10 Discrete output 1 – Terminals 3 & 4 (Channel B) – External power
3–30 VDC
Note: See Figure 6-15 for recommended
resistor versus supply voltage.
Excessive current will damage the transmitter.
Do not exceed 30 VDC input. Terminal current must be less than 500 mA.
